I built a hoist on a basketball pole that I had on the side of my driveway. (took down the rim and backboard, built arms extending out with pulleys and a rope) that I used for lifting the tub off, also used for taking the hard top off and on, lowering heavy duty bumper into place to bolt up, etc. I have had to do most of the work alone (since my youngest went away to college) so having a hoist of some sort is helpful. I built a dolly for the tub much like the one mentioned previously but I used the galvanize steel supports (Home Depot elec dept) for the base (wood 2x8 for the "cross pieces) so I could use motorcycle tie downs to secure the tub (the elec supports have holes drilled along the front for hooks). I also used casters , with brakes, (Home Depot). This "rig" allowed me to keep the tub strapped and use a floor jack to raise one end and put up on jack stands (the whole rig) to sand blast the bottom prior to paint, move it around to access different areas. Since the original build I have built a "crane" into my garage by filling the gap between two studs with 4X4s and hanging an I beam across the span to pull motors, tubs, tops, etc. (single car side, 8' door, spaced just behind roll up door when full opened). The 4x4's are cheap, and the I beam came from a metals recycler. I am adding a hook on rollers (Tractor Supply) this week that will slide along the length of the I beam. Hope this helps.
